f 'Applicationfiled January 22, 1909.. Serial No. 73,659.

To all it may) concern: Be it known that I, FRANK ABLE, Jr., a

citizen of the United States, .residing at Louisville, in-the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements m Turn1ng and Smoothing Devices for Phonograph- Records, of which the following is a specification.

This invention relates to turning and smoothing means, and particularly to means for turning. and smoothing phonograph records, and has for an object the provision of a cutter and holding means therefor-that will cause the I cutter to evenly and. smoothly turn or shave a phonograph record.

Another object of the invention is the provision of a plate adapted to fit into the reproducer arm of a phonograph and a cutting tool adj ustably securedthereto which in turn 'is adapted to shave orturn a phonograph record evenly, smoothly and perfectly true.

With these and other objects inview the invention comprises certain novel construc tions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a top plan view of one embodiment of the invention. Fig. 2 is a bottom plan view of the structure shown in Fig. 1. Fig 3 is a section through Fig. 1 approximately on line 33.

- phonograph. and by means of an adfustable rod the tool holder may be moved toward or In constructing a turning or shaving device according to the present invention I provide a diaphragm plate which fits in the reproducer arm of a phonograph and to this plate secure a pivotally mounted tpol suport or holder. A tool is so mounted in this older as to present its cutting edge to the record when the reproducer is mounted on a from the record for causing a heavy or light out to be made'wlien the record is turned.

" In this'manner a new blank or an old record may be shaved or turned smoothly and evenly preparatory to receiving 7 a record thereon. I

In order that the invention may be more .tool holder 2 is formed with a socket 3 into which isplaced one end of a tool 4. The tool 4. is held in place preferably by a set screw 5 and also preferably has its lower end in engagement with the bottom of socket 3 though it is not necessary. If desired tool .4 may be moved outward so that its lower end will be a considerable distance from the bottom of socket 3 and yet be firmly held in position by set screw 5.

The tool holder 2 is pivotally connected at its lower end to plate 5 by pin 6 and is pivotally connected at its upper end to,- art adj usting rod 7. The adjusting rod 7 extends-from its pivotal point on tool holder 2 to and through an aperture in plate 1. The end of rod 7 passing through plate 1 is threaded for any, desired distance in order to accommodate an ad ustmg wing nut 8. Surrounding 7 rod 7 and positioned between plate 1 and tool holder 2 is a spring 9 which has a tendency to force outwardtool holder 2. By the use of spring 9 the tool 4 is held yieldingly to its work and by theuse of rod 7 and nut 8 the position of the tool is regulated.

In operation plate 1 is placed in a reproducer arm on a phonograph and tool 4 set by properly adjusting nut 8. After the tool has been properly set the phonograph is started and as the record revolves the tool removes all former incisions or records'or if a blank is placed in the machine it is simply turned smooth and true. If the first cut does not remove all the incisions of a previous record a second cut may be taken as will be evident.

In the use of tools a cutter may be used constructed simply of a piece of steel that will take a fine edge or if desirable a tool may be made with a sapphire poin or cutting end.

What I claim is: v

1. In a device of the character described, a plate, a tool holder secured to said plate, a tool secured to said tool holder, a rod pivotally secured to said tool holder, and a nut threaded to said rod and acting against said late for moving said rod whereby said tool older and said tool are adjusted.

2. In a device of the character described, a plate, a tool holder secured to said plate, a tool secured to said tool holder, a rod pivotally secured to said tool holder, means acting against said plate to move said" rod in one direction, and means positioned between said tool holder and said plate for movingsaid tool holder in the opposite direction, the movement of said rod being adapted to vary the position of said tool and said tool holder.

3. In a device of the character described, a plate, a tool holder connected to said plate, a tool secured to said tool holder, a rod secured to said tool holder, means threaded on to said rod for moving the rod in one direction, and a spring for moving the rod in the opposite direction, the} movement of said rod being adapted to vary the position of said tool holder and said tool.

4. In a device of the character described, a plate, a tool holder pivotallyj connected therewith, a' tool secured to said tool holder,

a rod pivotally connected with said tool holder, means threaded on said rod for moving said rod in one direction, and a spring surroundin said rod and positioned between said too holder and said plate for moving said rod in an opposite direction, the movement of said rod varying the position of said tool holder and said tool.

In testimony whereof I aflix my signature in presence of two witnesses.
